Company Overview

Docusign brings agreements to life. More than 1.8 million customers and more than a billion people in over 180 countries use Docusign solutions to accelerate the process of doing business and simplify people’s lives. With intelligent agreement management, Docusign unleashes business-critical data that is trapped inside of documents. Until now, these were disconnected from business systems of record, costing businesses time, money, and opportunity. Using the Docusign AI-native IAM platform, companies can create, commit, and manage agreements with solutions created by the #1 company in e-signature and contract lifecycle management (CLM).

What you’ll do

As a Machine Learning or Software Engineer, you will contribute to ML model development and build the production software that enables Trust and Safety and Fraud detection. This role combines hands‑on machine learning with ownership of backend services, APIs, integrations, and data pipelines that turn model outputs into detection and prevention capabilities. You will work with senior ML and software engineers, Trust and Safety, Fraud, Service Protection, Product, and Data teams to deliver reliable solutions as signals and abuse patterns evolve.

This position is an individual contributor role reporting to the Director, Trust and Safety.

Responsibility

• Develop, test, evaluate, and deploy ML models for fraud, spam, abuse, risk scoring, and anomaly detection
• Build backend services, APIs, integrations, and data pipelines that support ML‑driven detection and prevention
• Integrate models and risk signals into production applications, decisioning systems, and automated interventions
• Work with senior ML engineers and domain experts to define signals, features, labels, and evaluation approaches
• Evaluate model performance and tune precision, recall, and false‑positive and false‑negative tradeoffs
